PhD Students

Miss Hortense Boudjou, PhD Student in “Elliptic Curves Cryptography” at the University of Maroua (Cameroon)

Scientific interests : I’m working on “Randomness Extraction over Elliptic Curves” under the supervision of  Prof. Kolyang (University of Maroua ) and  Prof.Djiby Sow (University Cheikh Anta Diop, Dakar).

My objective is to study construct efficient and cryptographically secure randomness extractors form products of subgroups of (hyper)elliptic curves. To achieve this goal, we will need deep knowledges on Analytic Number Theory, Algebraic Geometry, Probabilities and Statistics.

Starts from October 2011, ends on July   2016

Research Area : Elliptic Curves Cryptography, Randomness Extraction, Number Theory

Diploma : Master II

Miss Nafissatou Diarra, PhD Student in “Elliptic Curves Cryptography and Gröbner Bases at the Cheikh Anta Diop University of Dakar

Scientific Interests : I’m working on Deterministic hashing over (hyper)elliptic curves and Gröbner bases over DA-rings under the supervision of Prof. Djiby Sow (University Cheikh Anta Diop, Dakar).

My objective is to study construct deterministic and polynomial-time encodings over (hyper)elliptic curves. On the other hand, I also study Gröbner bases over DA-rings

Starts from October 2014 ends on  July 2016

Research Area : Elliptic curves, Gröbner bases

Diploma : Master II

Mr. Ousmane Ndiaye, PhD Student in Mathematics  at the Cheikh Anta Diop University of Dakar, Senegal

Scientific Interests : I’m working on  “Post-quantum Cryptographic Protocols and Critical Attacks” under the supervision of the Pr. Cheikh Thiécoumba Gueye (University Cheikh Anta Diop, Dakar).

The aim of my PhD project is to investigate the safety of cryptographic protocols based on the theory of error correcting codes (encryption, and authentication or signature) and arithmetic networks to propose necessary changes to their software implementation or installation on a embedded device.

Starts from oct-2013 ends on oct -2016

Research area : Coding Theory, Lattice Theory, Post-Quantum Cryptography

DiplomaMaster II
